Abstract
The invention relates to the field of wind power generation blades, in particular to a fan blade curing process. The fan blade curing process consists of the following steps of: a, matching a mold of a blade, and sealing the root end of the mold; b, placing two air outlets of a hot-air fan on the front and back edges of a blade tip in a blade tip opening, wherein the air inlet of the hot-air fan is positioned in the middle of a shearing rib of the blade; and c, starting the hot-air fan, and curing and heating the blade through circulating air. The conventional indirect heating way is changed, air in a shell is heated by adopting the hot-air fan according to the characteristic of hollowness of a thin shell of the blade, and the blade shell and an adhesive are heated directly through hot air, so that the electric energy loss is reduced by 70 percent, and a good blade curing effect is achieved.
Description
?
Technical field
The present invention relates to the wind power generation blade field, be specifically related to a kind of fan blade curing process.
Background technology
At the wind blade production industry, most of blade all is the glass fiber compound material of epoxy resin-matrix, because of epoxy resin and the adhesive that is used for bonding upper and lower half module, solidify under field conditions (factors) that not only cure cycle is long, and solidify not exclusively, this just need to carry out extra concurrent heating to reach solidifying requirements when solidifying.Traditional way is to lay copper pipe at mould inside when production mould, take water as heat medium.By after the water heating heat being passed to mould, there is again mould to conduct to blade, conduct to adhesive by blade again, transmittance process is complicated, and thermal losses is large.
The present invention changes traditional indirect mode, utilizes the characteristic of the shell hollow of blade, adopts air-heater to the air heat in the housing, directly heats blade shell and adhesive by hot-air, and electric energy loss reduces 70%.
Summary of the invention
Technical purpose of the present invention is to overcome the problems of the prior art, provides that a kind of completion of cure, energy loss are little, the fan blade curing process of energy-conserving and environment-protective.
For realizing purpose of the present invention, the technical solution used in the present invention is: the fan blade curing process is made of following steps: a vane mold matching seals the mould butt; B is at the blade tip opening part, and two air outlets of air-heater are positioned over the blade tip front and rear edge, and the air inlet of air-heater is positioned in the middle of the shearing ribs of blade; C opens air-heater, by circulated air blade is cured heating.
Aforesaid fan blade curing process, the front and rear edge of blade tip are as the air outlet of heating, and air draught in the middle of the shearing ribs forms the heating that loops of a sealing.
The present invention changes traditional indirect mode, utilizes the characteristic of the shell hollow of blade, adopts air-heater to the air heat in the housing, directly heats blade shell and adhesive by hot-air, and electric energy loss reduces 70%, and is good to the solidification effect of blade.
Description of drawings
Fig. 1 is the schematic diagram of fan blade curing process of the present invention;
Wherein, 1 shearing ribs, 2 air outlets, 3 air inlets, 4 air-heaters.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail: the present embodiment is to implement under the prerequisite in technical solution of the present invention, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, the fan blade curing process is made of following steps: a vane mold matching seals the mould butt; B is at the blade tip opening part, and two air outlets 2 of air-heater 4 are positioned over the blade tip front and rear edge, and the air inlet 3 of air-heater 4 is positioned in the middle of the shearing ribs 1 of blade; C opens air-heater 4, by circulated air blade is cured heating.The front and rear edge of blade tip is as the air outlet 2 of heating, and air draught in the middle of the shearing ribs 1 forms the heating that loops of a sealing.Wherein arrow represents the flow direction of wind.
The rear heating period behind the vane mold matching, because of the difference of the ply gage at each position of blade, institute's calorific requirement is different (place of cloth bed thickness, caloric value is large during precuring, curing degree is relatively high) also, therefore the front and rear edge of blade tip is as the air outlet of heating.
At blade tip place opening, utilize the characteristics of the double-shear rib of blade, send at front and rear edge to add hot blast, air draught in the middle of the shearing ribs, thus form an airtight circulating-heating.
Above demonstration and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (2)
1. fan blade curing process, be made of following steps: a vane mold matching seals the mould butt; B is at the blade tip opening part, and two air outlets of air-heater are positioned over the blade tip front and rear edge, and the air inlet of air-heater is positioned in the middle of the shearing ribs of blade; C opens air-heater, by circulated air blade is cured heating.
2. fan blade curing process according to claim 1 is characterized in that: the front and rear edge of blade tip is as the air outlet of heating, and air draught in the middle of the shearing ribs forms the heating that loops of a sealing.
